Abstract
An electro-optic polymer waveguide device capable of decreasing a driving voltage and an optical loss is disclosed. A vertical tapered waveguide is formed between passive waveguides of input and output portions in a waveguide and an electro-optic modulating region, and an amplitude of a waveguide mode of the input and output portion waveguide is equal to that of a optical fiber, thereby minimizing a connection loss with the optical fiber.
